Challenge: Adding a Comment

The code from the previous task is given.

In this case we used a mathematical formula inside the statement to calculate the area of a Trapezium. However, looking at the expression, the structure of the formula is not very obvious at first glance. In situations like these it is useful to add a comment so that other people reading the code can know what's going on, or even ourselves in case we revisit this code sometime later.

Add a single-line comment before the console.log statement, containing the following text:

Area of a Trapezium = (a + b) * h / 2
